Clad 7475 aluminum alloy in T61 temper is a high-strength aerospace aluminum with zinc, magnesium, and copper alloying elements, featuring a protective pure aluminum cladding layer that provides superior corrosion resistance while maintaining exceptional bearing strength and fatigue resistance for critical airframe components. T61 condition achieves its properties through solution heat treatment and controlled aging, delivering yield strengths in the 435–460 MPa range with good damage tolerance suitable for aircraft wing and fuselage structure applications per AMS 4207 specification.
